6.2.1 Sample preparation
NOTE
Use only capillaries from BUCHI. They are precise and adequate for this kind of operation. Other
capillaries have other dimensions and wall thicknesses. Using others may result in results that are
incorrect.
Each sample has to be prepared.
The following methods to compact the samples are recommended:
• Using the Sample Loader M-569
• Knocking the capillaries on a hard surface.
NOTE
Sample preparation by letting the capillaries fall through a tube is not advised, because cross
contamination may occur.
